Every daylight saving time change in the world, on the timelines of your cities: when the clocks go forward or back in each country, at the moment it happens and at your local time.
The US and Canada change on the second Sunday of March and the first Sunday of November, at 2:00 am in each time zone, so the change rolls west hour by hour from Newfoundland to Alaska and the Aleutian Islands. Europe changes on the last Sunday of March and of October at the same instant everywhere, 01:00 UTC. In the southern hemisphere it is the other way round: New Zealand, south-east Australia and Chile move their clocks back in April and forward in September or October. Israel, Palestine, Lebanon and Egypt have rules of their own.
The rules keep changing. In 2026 British Columbia, Alberta, Manitoba and the Northwest Territories stopped changing their clocks, and Morocco returned to GMT for good. The calendar is built from the IANA time zone database, the source your phone and computer use, and is updated with each of its releases.
Select a change to see how far the clocks move, the local time before and after for each offset, the countries and largest cities that change, and the date of the next change there. When two of your cities change on different dates, as the US and Europe do for a few weeks each spring and autumn, the timeline shows the gap between them shifting.
In the US and most of Canada on 14 March and 7 November, at 2:00 am local time in each time zone. In Europe on 28 March and 31 October, everywhere at 01:00 UTC. In New Zealand on 4 April and 26 September, in New South Wales, Victoria, Tasmania and the ACT on 4 April and 3 October.
The US moves its clocks forward two weeks before Europe and back one week after it. For those three weeks New York is four hours behind London instead of five, and the timeline shows the shifted gap between your cities.
The US, Canada (except the provinces that stopped), Mexico’s border cities, Cuba, Greenland, the European Union, the UK and the rest of Europe except Russia, Belarus, Turkey and Iceland, Israel, Palestine, Lebanon, Egypt, Chile, New Zealand and south-east Australia. Each event on the timeline lists its countries and largest cities.
No. British Columbia moved its clocks forward for the last time on 8 March 2026 and stays on that time all year; Alberta, Manitoba and the Northwest Territories did not move their clocks back on 1 November 2026. The rest of Canada still changes.
At 2:00 am British Summer Time on the last Sunday of October, when the clocks go back to 1:00 am GMT; they go forward at 1:00 am GMT on the last Sunday of March. In 2027 that is 31 October and 28 March.
